Abstract

A method for receiving a broadcast service is provided. The method comprises the steps of: receiving a first packet stream; extracting presentation time information from a header of said first packet stream; extracting trigger information including a target service identifier and a trigger action from a payload of said first packet stream; and The triggering action is executed on the object corresponding to the target service identifier at the time indicated by the presentation time information.

Description

technical field [0001] The present disclosure relates to a method for transmitting a broadcast service, a method for receiving a broadcast service, and an apparatus for receiving a broadcast service. Background technique [0002] Digital television (DTV) is now presented to provide various services in addition to the original functions of television (TV) such as playing video and audio, for example, broadcast information such as electronic program guide (EPG) can be provided to users, and users can be simultaneously Broadcasting services from at least two channels are provided. In particular, since the receiving system of DTV includes a large-capacity storage device and is connected to a data communication channel and the Internet (which can be used for two-way communication), more services can be obtained through broadcast signals. In addition, as services provided through broadcast signals become more diverse, the need to accurately utilize the diverse services increases....
